Apparent murder-suicide leaves 4 dead, including 2 young children

Fresno police are attempting to piece together a shooting spree that left four dead, including two young children, in an apparent murder-suicide.

Police were called Sunday morning to a ground-floor apartment and found a man outside with a stab wound, the Fresno Bee reported.

The officers then heard a gunshot and went in the apartment, where they discovered a woman in her 20s, believed to be the stabbing victim's wife, dead from an apparently self-inflicted gunshot wound, the newspaper reported.

Police also found the bodies of the couple's two children -- an 18-month-old girl and a 3-year-old boy -- and another man, all fatally shot.
